To all whomit may concern:

Be it known that I, THoMAs NATHAN'RUS SELL, a citizen of the UnitedStates, and a resident of Chicago, in the State of Illinois,

a have invented certain new and useful Improvements in v()arlines, ofwhich the follow infi/iis a specification.

y present invention relates general to car construction and moreparticularly 1 to the bodies thereof and has special reference toimprovements in the carlines used in framing car roofs, and'mostspecifically to end carlines or end plates.

The principal ob ects of my present invention are the provision in abody con struction involving the use of metallic members, of a carlinewherein a given weight of metal is most advantageously employed in theproduction of a body of maximum. rigidity and strength, a minimum ofweight, simplicity of manufacture, avoidance of waste of material,andlow cost; the pro" vision of an improved arrangement of corn hinedend carline and filler block forming an end plate construction; theprovision of an improved carline construction which is adaptable foremployment as, a component part of a composite end plate construction;the provision of improved means for securing the end plate in turn tothe other members of the car framing in order to secure the greateststrength and rigidity of the frame, and roof construction and attain thegreatest resistance to all bending moments and other stresses, togetherwith such other objects as may hereinafter appear.

In attaining the foregoing objects and certain additional advantages tobe'below disclosed, I have provided the construction illustrated in theaccompanying drawings,

wherein:

Figure 1 is a perspective view of the carline before the filler block isplaced in position to form the composite end plate structure;

Figure 2 is a plan view of the composite end plate structure;

Figure 3 is a view of the blank from which the carline is manufactured;

Figuresd and 5 are transverse sectional views of the composite end platestructure taken on the lines fl-.4:'and 5--5 of Figure 2, each showing,however, a fragment of a roof purlin in position and supported by aflange of the end carline;

Figure 6 is a fragmentary view, partly in vertical section, of, a cornerof a car body structure, illustrative of the method of attaching thecomposite end plate structure to such body;

Figure 7 is a sectional. view taken on the line 7-7 of Figure 6.

Referring first more particularly to Figures-1, 2 and 3 of the drawing,it will be observed that in manufacturing the carlines 20, embodying mypresent improve ments, I preferably employ a fiat rectangular piece, 30,(Figure 3) of sheet or plate metal, or similar suitable material, andpress outwardly oppositely inclined flanged portions 31, 32, by bendingthe sheet along the longitudinal line indicated at 33 until the portions31, 32,

named tension portions are formed by bending, the sheet along the lineindicated at 36, and simultaneously giving the web 37 thus formed themarkedly curved S section clearly to'be seen on viewing Figures at and5, there being no sharp bonds at the points a and b. The carline 20 ofsaid Figure l and the composite end plate 19 are of substantially thesame construction, save that in the composite end plate the end carlinesupport a filler-block indicated at 19".

By the employment of suitable dies, cutoutsmay be made as indicated at39, 39, for the formation of brackets 40, 40 (see Fig" ures 1 and 3),adapted to bear against the side plates of the body framing, one indicated at 17, Figure 6), when secured in position, as by bolts 41,bracing the composite end plate or end carline against horizontal orrocking movementrelatively to the'side plates 17, the formation of saidbrackets 40-.40 leaving outwardly projecting hangers 42-42 by means ofwhich the carline may also be suspended from the plates 17,

bolts 43 (Figure 7) being conveniently employed for securing the carlinein predetermined osition. 1

As will be'apparent on inspection of Figure 1, the formation of myimproved composite end plate or carline by the method just describedwill provide oppositely inclined compression surfaces 31, 32, graduallyincreasing in width from the center of the carline 20, toward the endsthereof and thereby giving a. maximum width to the projecting hangerportions 42, 42,-whereby an additional bracing effect againstliorizontalstrains may be attained, the method referred to further providingtension surfaces 34 and 35, thereby affording a maximum amount of,material for the formation of the brackets On viewing Figures 1, 6 and7, it will be observed that for the purpose of bringing the ends of theroof sheathing directly down upon the ends of the carlines, that is,upon the hangers 42 thereof, and thereby when intermediate purlins 18are employed, avoiding the necessity of using filler blocks at suchends, I provide the carlines with bends as in dicated at 441 44*,whereby the principal advantages of my present construction are allretained, but the roof construction is somewhat simplified.

On viewing Figures 4 and 5 it will be observed that the compressionsurfaces 32 and tension surfaces 35 are preferably extended in oppositedirections relatively to the curved web 37, this affording a rest orsupport for the filler block 19 of the end plate 19 as is clearly to beseen from inspection of such figures.

Referring now more particularly to Figures 6 and 7, it will be observedthat the end posts 21 as here shown are of I-beam construction, theouter ends of the web 44 being cut away from the flanges and bent at aright angle to the body of such web as indicated at 45, whereby they maybe attached to the composite end plate structure 19.

' The improved structure of carline de scribed in the foregoingspecification has certain marked features of advantage among which maybe noted the,rearwardly extending flanged surface 3132 which supportsthe purlins 18 and is in turn supported and braced by and against theside plate 17 by the hangers 42 and brackets 40; the forwardly extendingflanged surface 34-35 which supports the filler block 19 to which may benailed the sheathing 53; the curved web 37 which is arranged at an angleto the perpendicular and is therefore more rigid and offers greaterresistance to twisting strains than would be the case were the webposition and tying to other portions of the body or roof structure, suchfeatures of construction, however, being claimed in mycopendingapplication, Serial No. 814,519, filed January 26, 1914, of which thisapplication is a division.

Having thus described my invention and illustrated its use, what I claimas new and desire to secure by Letters Patent, is the following:

1.. A carline having a compression surface and a tension surface ofdifi'erin contours, the latter having an outer edge ying in a singlevertical plane and an obliquely arranged curved web therebetween theupper edge of which lies in a vertical plane parallel to saidfirst-mentioned plane, said compression surface and said tension surfacebeing disposed laterally in opposite directions from said web, and thesum of the width of the parts being substantially the same incrosssection throughout the carline.

2. A carline having a compression surface, a tension surface, a webtherebetween, said web being obliquely'arranged, whereby the compressionsurface and tension surface lie in ,part one above the other, and afiller block supported by a projecting edge of one of said surfaces.

3. A carline having a compression surface, a tension surface, a curvedweb therebetween, said' web being obliquely arranged, whereby thecompression surface and tension surface lie in part one above the other,and a filler block supported by a projecting {edge of one of saidsurfaces.

sion surface and an inclined web therebetween formed with connectingportions of large radius of curvature, said compression and tensionsurfaces being disposed laterally in opposite directions from said weband arranged to lie in part one above the other.

6. A carline having a compression surface, a tension surface, anobliquely arranged web therebetween, said compression surface and saidtension surface bemg disposed laterally in opposite directions from saidweb and arranged to lie in part one above the other.

7. A. carline having a compression surface, a tension surface, a webtherebetween, the two longitudinal halves of the web lying in planesintersecting in plan view at an angle adjacent the center of thecarline.

8. A carline having a compression surface, having one edge lying in asinglevertical plane, a tension surface having one edge extending beyondsaid first mentioned edge and lying in a single vertical plane parallelto said first mentioned plane, said tension surface being arranged tolie in part below said compression surface, said tension surfaceincreasing in width progressively towards the center of the carline, andan inclined web connecting said compression and tension surfaces.

9. An S-shaped carline having a curved web portion and a lower flangeprojecting beyond the curved part of the Web connecting the upper andlower edges of the carine.

10. A pressed-steel carline having a substantially Z-shapedcross-section and comprising a web extending longitudinally thereof, andan upper flange and a lower flange projecting horizontally from said webin opposite directions, said upper flange increasing in width from themiddle of the carline toward the ends thereof, said lower flangedecreasing in width from the middle of the carline towards the endsthereof. 1

In testimony whereof I have hereunto signed my name in the presence ofthe two subscribing witnesses.
